Claims

[Scope of Claim for Utility Model Registration] (1) Exposure in which both ends of a flash lamp are positioned and held by reflector side plates via rubber bushings, and the light beam emitted from the flash lamp is irradiated onto the document via the reflector to perform exposure. An exposure apparatus characterized in that the apparatus is provided with means for preventing the flash lamp from rotating around its axis with respect to the reflector. (2) The exposure apparatus according to claim 1, wherein the flash lamp rotation prevention means is one that adheres an end of the lamp to a rubber bushing and a reflector side plate. (3) A request for utility model registration characterized in that the above-mentioned flash lamp rotation prevention means fixes an electrode provided near the end of the lamp for drawing out the trigger wire of the lamp to the side plate of the reflector. Exposure apparatus according to scope 1. (4) Utility model registration claim 1, characterized in that the above-mentioned flash lamp rotation prevention means is such that at least one of the anode electrode and the cathode electrode at both ends of the lamp is fixed to the reflector side plate. Exposure device described in Section 1.
